This vintage plaid mackinaw coat was made in the mid 1930s for Sears under the Hercules workwear label. This coat was also made under the Fieldmaster hunting label for Sears at the same time, however the hunting version has a game pouch, while this, the workwear version, does not. The coat is made from red and black plaid mackinaw cloth, with double shoulders and two-way pockets (top entry cargo pockets over side entry handwarmers). As was typical of work coats of this period, it is unlined.

Chest (pit to pit): 24″ (doubled = 48″)
